The Peugeot 8HP (DV4C) is a 1,398 cc, inline‑four turbo‑diesel engine produced between 2002 and 2006. It features an 8‑valve SOHC layout with indirect injection and a fixed‑geometry turbocharger, delivering 50 kW (68 PS) and 160 Nm of torque. This compact engine prioritized fuel efficiency and low‑end tractability for urban driving.
Fitted primarily to the 206 and 207 city cars, the 8HP was engineered for economical, low‑stress commuting. Emissions compliance for its production period was achieved through basic exhaust aftertreatment, enabling adherence to the Euro 3 standard across its core European markets.
A documented reliability concern involves premature failure of the vacuum pump for the brake booster, potentially leading to reduced braking assistance. This issue, referenced in PSA Group Service Bulletin 08C003, is often attributed to seal degradation. The pump design was revised in later production runs to improve sealing integrity.
Production years 2002–2006 meet Euro 3 standards (VCA UK Type Approval #VCA/PSA/8HP).
The Peugeot 8HP (DV4C) is a 1,398 cc inline‑four turbo‑diesel engineered for city cars (2002-2006). It combines indirect injection with a fixed‑geometry turbocharger to deliver adequate low‑speed torque for stop-start driving. Designed to meet Euro 3 standards, it prioritizes fuel economy over outright performance.

The fixed-geometry turbo provides adequate low-RPM torque for city driving but lacks refinement. Strict 40,000 km or 24-month timing belt replacement is mandatory to prevent interference engine damage. PSA B71 2290 (5W-40) oil is recommended. The Bosch VP37 injection pump is robust but sensitive to fuel quality; only ultra-low-sulfur diesel (ULSD) should be used. The vacuum pump for the brake booster, integrated into the camshaft, is a known failure point; listen for hissing noises and ensure prompt replacement per PSA SIB 08C003 to maintain braking performance.
Oil Specs: Requires PSA B71 2290 specification (PSA Service Schedule). Equivalent to ACEA B3/B4.
Emissions: Euro 3 certification applies to all 2002–2006 models (VCA Type Approval #VCA/PSA/8HP).
Power Ratings: Measured under ECE R85 standards. Output is consistent across model range (PSA Group PT-2004).

The Peugeot 8HP (DV4C) was used across Peugeot's PF1 platform with transverse mounting. This engine received minimal platform-specific adaptations and no significant facelift revisions occurred during its production run, ensuring broad parts compatibility. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat machined surface at the front of the cylinder block, near the timing belt cover (PSA Repair Manual 8HP). The 8th digit of the VIN is 'F' for this 1.4 HDi 68 engine variant. Visually, it can be identified by its black plastic rocker cover and the Garrett turbocharger mounted at the front. Critical differentiation from the later DV4TD: The 8HP uses a Bosch VP37 rotary injection pump, while the DV4TD uses common rail. Service parts, particularly the timing belt and injection pump, are specific to the 8HP and not interchangeable with later DV4 variants.
The 8HP's primary reliability risk is vacuum pump failure for the brake booster, with elevated incidence in high-mileage vehicles. PSA internal data indicated a notable failure rate before 150,000 km in affected batches, while owner reports frequently cite a hissing noise and reduced brake pedal assistance. Seal degradation is the primary cause, making prompt replacement critical for safety.
Analysis derived from PSA technical bulletins (2002-2006) and owner-reported failure data (2006-2023). Repair procedures should follow manufacturer guidelines.
